A charity supporting people with epilepsy left in financial limbo by the collapse of electronics retailer Dick Smith has been handed a funding lifeline.

Retail Food Group, the owner of Brumby’s bakeries, Pizza Capers and Donut King, has stepped in to provide Epilepsy Action Australia with a $50,000 donation, matching a gratuity Dick Smith promised last year.

Cash-strapped Dick Smith was the major funding sponsor of EAA before it went into receivership this month.

The charity’s chief executive, Carol Ireland, said the loss of sponsorship would have put a major dent on its fundraising abilities.

“In losing that Dick Smith agreement, we lost not only the $50,000 sponsorship, but up to $100,000 worth of merchandise being sold through their stores,” Ms Ireland told AAP.

She said RFG had stepped in during a “time of crisis” for the organisation.

“They’ve got some amazing brands that are so well known. Everybody knows the brands,” she said.

RFG has committed to sponsoring the charity’s biggest fundraising event, Purple Day, to be held on March 23, Ms Ireland said.
